    FANTASIC TIRE

    Love the looks and the traction I get. I don't use "trails" as most of my riding is in the bush.

    GERALD in CA

    Good tire, but not foe me.

    Very nice tire with good build quality. Bad part is my 2018 X3 Max Turbo R blows the tire away. Other thing is the tire does measure 30 inches as implied in the tire size. Should be okay for the 120 hp machines. These are going up for sale. My loss.

    Andrew in OK

    Limited use so far, but these seem like great tires...

    We bought some of these tires to go won some ITP wheels for my son's Yamaha Raptor 80. His old tires were worn and new 7" tires were not easy to find. The tires were a real improvement compared to our last ride on the old tires. I would have rated them higher, but we just got them, so it's hard to speak accurately about tread life.
